HEADLlGHT-ADJUSTER.

SPECIFICATION forming` part of Letters Patent No. 792,550, dated June13, 1905.

Application tiled October l2, 1904. Serial No. 228,186.

To n/ZZ whom, it 77u03/ concern:

Be it known that I, PETER PETERSON, a citi- Zen of the United States,residing at Lexington, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Headlight-Adjusters, of which the following is a specification.

This invention relates to headlights such as are pivotally mounted uponelectric cars or locomotives in such manner as to direct the light alongthe track in rounding a curve.

The objects of the invention are to improve and simplify theconstruction of such devices.

Tith the foregoing and other minor objects in view, which will appear asthe description proceeds, the invention resides in the particularcombination and arrangement of parts and in the precise details ofconstruction hereinafter described and claimed as a practical embodimentthereof.

In the accompanying drawings, Figure 1 is a view illustrating theimproved mechanism applied to an ordinary form of electric car. Fig. 2is a view illustratingin separated relation the various parts of themechanism.

Like reference numerals indicate corresponding parts in both figures ofthe drawings.

The dotted lines in Fig. 1 indicate'an electric car, on the rear side ofthe front board 1 of which is attached a suitable ear or lug, such as 2,in which is journaled the upper end of a vertical shaft 3, having acrank portion 4 extending' forward through suitable slots in the frontboard. Attached to the crank portion 4 in advance of the front board 1are laterally-extending arms 5, having angular terminals 6, adapted to taround and hold in position a headlight, suoli as 7. The lower end ofthe vertical shaft 3 is journaled in any suitable manner in thecar-platform 8 and is provided at its lower end with a bevel-gear 10,with which is meshed a bevel-gear 11 upon a horizontal shaft 12,journaled in bearings 13 beneath the car-body. Adjustable collars 14,having tightening-screws 15 therein, as shown in Fig. 2, are placed uponthe shaft 12 in order to maintain the bevel-g'ears 10 and 11 in meshwith each other. To the rear end of the shaft 12 is rigidly secured inany suitable manner an angular extension, 16 to the lower end of whichaforked member is suitably attached, as indicated at 18. The forkedmember 17 straddles a pin 19, which is secured in any suitable manner toan upright 20, carried by the pivotal Wheel-truck 21 of the car.

The operation of the improved construction will be apparent from theforegoing' description. When the car-truck turns while the car isrounding a curve, the pin 19, through the medium of the fork member 17,causes the shaft 12 to rotate. The rotation of the shaft 12 istransmitted to the crank-shaft 3 in such manner that the headlight7 isturned so as to direct its rays along the track.

By providing a fork member, such as 17, to engage a pin, such as 19,mounted upon the pivotal truck of the car, said truck may be permittedto have up-and-down movement with respect to the car-body through themedium of suitable springs Without permitting such up anddown movementto disarrange the headlight-operating mechanism.

Changes in the precise embodiment of the invention illustrated anddescribed may be made within the scope of the following claim withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

Having thus described the invention, what is claimed as new is- Thecombination with a car, having a front board formed with slots and apivotal truck, of a shaft journaled on the rear side of said front boardand having a crank portion eX- tending forwardly through the slotstherein, laterally-extending arms on said crank portion in advance ofsaid front board, angular terminals on said arms, a bevel-gear on saidshaft, a second shaft journaled on said car and having a bevel-gearmeshing with said firstmentioned bevel-gear, adjustable collars on saidsecond shaft an angular extension on said second shaft, a pin on saidpivotal truck, and a forked member on the angular extension of saidsecond shaft and st raddling said pin.

In testimony whereof I affix my signature in presence of two witnesses.

PETER PETERSON.
